Access control systems are a crucial component of parking lot systems. Many people report that the motors fail after only a year, the barrier arms vibrate excessively during operation, and they frequently break down. How should we choose a parking lot barrier?
I. Does the motor controller need to use variable frequency technology?
Variable frequency technology can control the motor's operating speed and torque, making the barrier arm operate more smoothly and reducing the impact force of the accelerator by 90%. This significantly improves the quality and lifespan of components, further enhancing the efficiency and controllability of variable frequency technology, reducing motor temperature rise, and eliminating the embarrassing situation of overheating motors in summer, frequent breakdowns, and the need to open the door to cool down.
II. Should the motor accelerator be a worm gear or a gear accelerator?
A worm gear is a complex acceleration mechanism that can reduce the motor speed to the same speed as the barrier arm's operation. It is very low-cost, but its efficiency is very low. Most of the drive energy input to the motor is consumed in this acceleration stage, causing the motor to overheat and potentially break down in slightly low-temperature environments. Furthermore, low efficiency means greater wear and tear, making it difficult to extend the lifespan of the parking gate. Standardized multi-stage gear acceleration is significantly different; the technology is mature, efficiency reaches over 90%, there is no overheating, and the lifespan is long.
III. Is the operating temperature range of the barrier sufficient?
Temperature range is one of the factors indirectly affecting the smooth operation of the barrier. We recommend purchasing a product with a wide temperature range of -40℃ to 75℃. For outdoor use, a wide temperature adaptability range is essential to ensure the barrier can operate easily in both high summer temperatures and winter.
IV. Are the chassis thickness and body weight sufficient?
The barrier needs to drive a very heavy and long barrier arm. Besides the motor accelerator, the load-bearing capacity of its components is also crucial. The chassis design must be robust, the steel plate thickness of the chassis should reach 2mm, and the weight of the parts should not be less than 50kg. Only in this way can severe swaying and deformation be avoided when driving a long lever arm under load.
The above are the aspects to consider when purchasing a parking access control system.
